Good point! I’m not sure why a fan coil requires a constant volume fan, but that’s apparently the case.
How about using a ZoneHVAC:UnitHeater? Heat transfer will be the same and the fan can be “On/Off”. This only works for heating, not cooling.
Another possibility to get cooling capability is a UnitVentilator. You’d have to define it with no outdoor air and a variable volume fan. If you make the variable volume fan coefficients proportional to load (100% load = 100% power, 50% load = 50% power, etc., it should end up very close to On/Off operation.

They would need to be connected to an airloop then right?
What if they are only set up as zonal equipment? if I use
availabilitymanager:nightcycle doesn't it only work if I can assign the
availabilitymanager:assignmentlist to something? I don't see where I can
include that into the fan coil at the zone level.
